早熟高油大豆新品种吉育203的选育与栽培要点

Breeding and Cultivation Techniques of High-oil Soybean Jiyu 203 with Early Maturity

为了选育适宜吉林地区种植的早熟高油大豆新品种应用于生产，以公交2059反一6为母本、垦农18为父本于2003年采取人工去雄授粉方法获得杂交后代，再利用系谱法鉴定选育出吉育203（原品系代号公交DY2008-9）。该品种2010-2011年在吉林省早熟组区域试验中的平均产量为2369．2kg／h㎡，比对照绥农28（2301．7kg／h㎡）增产2．9％；2011年在吉林省生产试验中的平均产量为2314．0kg／h㎡，比对照绥农28（2263．5kg／h㎡）增产2．2％；生育期118d，株高85cm左右，百粒重为20．1g，主茎节数16～18个，分枝1～2个，节间短，结荚均匀，荚密集，3～4粒荚多，荚熟褐色，完全粒率高，无褐斑粒，籽粒品质优良，脂肪含量24．94％，抗性好，于2011年通过吉林省品种审定委员会审定并命名，适宜吉林省大豆早熟地区及肆杰相仞抽．
